Method and apparatus for producing a photopolymerizing lithographic plate

摘要

Decrease in sensitivity can be avoided to obtain a stable and highly sensitized photosensitive layer in a process for preparing a photopolymerizing lithographic plate including a coating step and using rubber rollers before and after the coating site. This is achieved by excluding an antioxidant and/or aging retardant from at least the surface of rubber rollers placed before and after the coating site. The photopolymerizing lithographic plate excellent in its sensitivity as compared with the conventional one can be obtained.
